Title: Stacking device for sheet material especially veneer boards and cutting machine incorporating such a stacking device
IPC: B27L5/08
Filed: 1960-04-13
Abstract: 932,663. Delivering sheets. MULLER A.G. April 13, 1960 [April 13, 1959], No. 13266/60. Class 100 (1). A cutting machine for sheet material, especially veneer boards, has a frame comprising side members 1, 2 and cross-members 3, 4, the member 4 carrying a fixed lower knife 5 and the member 3 carrying means, not shown, for actuating beams 6, 7 which support movable upper knives 8, 9 respectively. Six hollow cylinders 14 are supported at one end in the member 4 and at the other in fish-plates 13 carried by a cross-bar 12 mounted on supports 11. A supporting bar 15 is mounted above each cylinder 14. In each cylinder 14 a piston 17 having a hollow rod 24 attached thereto is slidable, a further piston 18 having a rod 34 being slidable within the rod 24. A continuous strip of veneer 16 is advanced from a gluing machine over the bars 15 and between the knives 5, 8, 9 and after passing the knives rests on the extended piston rods 24, 34. When a predetermined length of strip has been fed past the knives the latter are actuated so as to cut-off a portion thereof; simultaneously, the rods 24, 34 are retracted into the cylinders 14 and the severed portion 49 of the strip falls on to a pile 50. The rods 24, 34 are then again extended so as to support the oncoming length of strip. The telescopic assemblies are pneumatically operated, air under pressure being supplied thereto through pipes 25, 33 alternately under the control of solenoid-operated valves 27. Measuring wheels 38 rest on the surface of the advancing strip 16 and control the operation of the knives which in turn controls the actuation of the valves 27. The telescopic assemblies are divided into two groups A, B, C, and D, E, F, Fig. 4, each group being controlled by one valve 27. The beams 6, 7 are coupled by locking means 10 if the strip 16 has a width corresponding to the combined length of the knives 8, 9, and the telescopic assemblies A-F are then operated in unison. If the strip is only half this width, however, the beams 6, 7 are uncoupled and one knife 8 or 9 only is used, one group of the telescopic assemblies being disabled. Two narrow strips of veneer may be cut side-by-side into sheets of either the same or different lengths, the knives 8, 9 and the groups A-C, D-F operating independently in the latter case. In a modification, when long sheets are to be cut, an additional range of six telescopic assemblies, identical to the assemblies A-F, is disposed opposite to and aligned with the assemblies A-F, the assemblies being alternately extended towards and retracted away from each other.

Title: Gear checking apparatus
Filed: 1956-05-01
Abstract: 811,341. Electric indicating systems. NATIONAL BROACH & MACHINE CO. May 1, 1956 [June 6, 1955], No. 13344/56. Class 40 (1). The dimensions of gear teeth are checked by means of a pair of independently movable sensing devices which engage simultaneously with two tooth surfaces of the gear and which are moved in a direction substantially parallel to the gear axis. As shown, the gear 80, the teeth of which are to be examined in succession, is clamped on the end of a work spindle 86 by a nut which engages on an interrupted thread. The spindle 86 is carried in sleeve 88 which is mounted in support 90. The sensing device 34 (v.i.) is carried on the cross-slide 72, itself supported on an intermediate longitudinal slide 28 and a main slide 24. The intermediate slide is adjusted longitudinally on the main slide. The main slide is then reciprocated longitudinally by means of a motor 36 which drives shaft 42, gearing 44, 46 and an adjustable throw crank mechanism 50, 58 to reciprocate the main slide through connecting lever 62. The head carrying the sensing device is moved radially with respect to the gear by a cam 70 sliding on a splined portion of shaft 42 and moving the slide by contact with the end of adjustment screw 72 against the action of spring 76. Thus, during the feed of the main slide the transverse slide is so positioned that the tooth under examination is gauged but is withdrawn at the end of the gauging stroke. The gear is moved around tooth by tooth by a lever 130 racked by a cam 132 on the shaft 42. The cam breaks a toggle 110, 112 against the action of a spring 122 and through a pawl 124 engaging in an indexing plate on the end of shaft 86 rocks the work shaft to index the gear one tooth. At the same time pawl 128 carried on an extension of sleeve 88 is forced out of engagement with the indexing plate. As lever 130 moves back locking pawl 128 drops into its recess holding the shaft 84 while the feed pawl rides out of its slot over the edge of the indexing plate and drops into the next one. The sensing device consists of feelers 190, 192 engaging the upper and lower side respectively of the tooth being engaged and so pivoted at 194 that their rear ends adjust cores in transformers 196. Recording mechanism.-As the slide 25 advances during a gauging stroke it pulls a tape 174 tensioned by a weight 186 over a roller 172 to drive a record chart 10 through shaft 170 and one-way clutch 171. The one-way clutch prevents movement of the chart during the return stroke of the slide. A pair of pens are moved each in accordance with the output of one of the sensing devices. A plot of the type shown in Fig. 1 is produced on the chart. Gauging helical teeth (Fig. 3).-A helical slot in a member carried on the sleeve 88 is engaged by a follower 216 carried by slide 25. Thus the sleeve is rocked during gauging and through pawl 128 similarly rocks the gear as the sensing fingers move horizontally.

Title: Electrical comparator network
IPC: G06F7/02
Filed: 1957-04-26
Abstract: 836,234. Comparing digital data. WESTERN ELECTRIC CO. Inc. April 26, 1957 [April 27, 1956], No. 13349/57. Class 106 (1). A comparator network for comparing two numbers in binary code is arranged to provide one of two possible outputs dependent on the relative magnitude of the two binary code numbers. Use is made of the fact that a first conventional binary code number equals or is greater than a second such number if the comparison of the complement of the second number with the first number reveals at least a " one " digit for each digit position except that corresponding digit positions need not contain a " one " digit if at least one corresponding more significant digit position in both numbers contains a one" digit. As described for comparing two numbers a 1 , a 2  . . . an and b 1 , b 2  ... b n  in conventional binary code, Fig. 1, the digit pairs a 1 , b 1 <SP>1</SP>; a 2 , b 2 <SP>1</SP>; &c. (where the dashed letters represent the binary complements of the corresponding undashed letters) are compared in the OR circuits 100, 120, &c. respectively and in the AND circuits 110, 130, &c., respectively. An output from each AND circuit 110, 130, &c. is fed to all the OR circuits of lower significance via the OR circuits such as 140. The outputs from the OR circuits 100, 120, &c. pass to a final AND circuit 160 arranged to provide one signal at its output 161 if all the inputs are " ones," and a second signal if at least one of the inputs is a " zero," thus indicating the relative magnitude of the numbers being compared. In a particular example (Fig. 2, not shown) the OR circuits 100 comprise pentode tubes, the AND circuits 110 comprise twin triodes, the OR circuits 140 diodes and the final output circuit 160 comprises a triode. As described for comparing one number c 1 , c 2  . . . c n  in conventional binary code with another number d 1 , d 2  ... d n  in reflected binary code (Fig. 3, not shown), a number e 1 , e 2  . . . e n  is formed by leaving d 1  unchanged and transferring any less significant digit of the reflected number d 1 , d 2  . . . d n  if the digit in the conventional number c 1 , c 2  . . . c n  of next greater significance is a " one " and comparing e 1 ,e 2  . . . en with c 1 <SP>1</SP>, c 2 1 ... c n <SP>1</SP> as described with reference to Fig. 1. Specifications 663,872, 789,660, 836,235, 836,236 and 836,237 are referred to.

Abstract: 133,800. Dyson, J. W., and Dawson, J. H. Oct. 29, 1918. Drawing-frames; sliver conductors. - Slivers, either as they are being drawn or as they pass from one part of a machine to another, e.g. as they pass from the calender rollers of a carding- engine to the coiler head, are combed, smoothed, and polished by being passed over one or more wires or small rods which may be in the form of a grid. Fig. 1 shows a device comprising three wire rings through which the sliver is passed on its way from the doffer of a carding-engine to the funnel leading to the calender rollers. The rings diminish in size and are in contact with the sliver all round. Fig. 6 shows a device to be attached to the coiler top of the carding- engine and comprises two sets of wires between which the sliver passes. The upper set is carried by a frame F hinged to the frame D which carries the lower set, and the distance between the wires is gradually diminished. The frame D is hollowed out at G where the sliver enters, and a shaped guide H delivers the sliver to the aperture in the coiler. Figs. 8 and 9 show a device adapted to be fixed to the calender roller cover of a drawing- frame and provided with a V-shaped guide M which doubles over and turns in the selvedges before passing them to the funnel. The wires L are fixed in the frames.
